Columella is a genus of very small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Truncatellinidae, the whorl snails and allies. [2]
Taxonomy
[edit]Columella is commonly classified within the Vertiginidae. However, as shown by Nekola & Coles (2016), the genus is not that closely related to the Vertiginidae, but may rather be affiliated with the Chondrinidae or form a pupilloid family of its own. A systematic revision is pending.[2]
